Description

Technical Field

[0001] This invention relates to the field of microwave signal generator technology, and more specifically, to a microwave signal generator with a high-power vacuum tube. Background Technology

[0002] Microwave signal generators are frequently used in the aerospace field. They are specialized signal generating devices that use frequency synthesis to produce specific microwave signals. Microwave signal generators are used in the system and performance evaluation of satellites and space shuttles. With the development of technology, the performance requirements for microwave signal generators are gradually increasing, such as microwave signal generators with internal high-power vacuum tubes.

[0003] Currently, microwave signal generators on the market with high-power vacuum tubes mainly use high-frequency vacuum tubes to generate high-power microwave signals with specific parameters, thus meeting various application needs. By incorporating an internal tuning microwave oscillator, tuning is convenient. Since microwave signal generators are often used in different work environments, a convenient carrying device is provided at the top of the generator for easy handling by the operator.

[0004] However, most microwave signal generators on the market currently use large-scale integrated circuits and lack external grounding devices for protection. This makes them prone to static electricity during debugging or maintenance, which can cause injury and damage to equipment, thus shortening their lifespan and posing a certain degree of operational risk. Furthermore, the lack of baffles on the outside of the microwave signal generator makes it impossible to limit the distance between the generator and the wall, which can easily block the heat dissipation vents, affecting heat dissipation and failing to provide adequate cooling conditions. Summary of the Invention

The bottom of the generator body is connected to the connecting block. Two push rods are connected to the outside of the connecting block via a rotating shaft. The left side of the push rod is connected to the rotating rod, and the rotating rod and the push rod are welded together. The rotating rod can rotate inside the second support plate. Two positioning devices are provided through the rotating rod, and the positioning devices on the left and right sides are mirror-distributed.

[0012] Optionally, the positioning device includes: brake pads, anti-slip pads, and triangular blocks. The upper end of the brake pads is irregularly shaped, and the bottom of the brake pads is connected to the anti-slip pads. A triangular block is fixed to the left side of the anti-slip pads. Two brake pads pass through the outside of the rotating rod, and two first gears also pass through the outside of the rotating rod.

[0013] Optionally, a grounding device is provided at the front end of the first gear, wherein:

[0014] The grounding device includes: a second gear, a winding rod, a soft copper wire, an upper interface, and a grounding body. The second gear meshes with the first gear, and a winding rod is provided between the two second gears. A soft copper wire is wound around the outside of the winding rod. The upper end of the soft copper wire is connected to the upper interface, which is connected to the outer shell of the generator body. A grounding body is provided at the end of the soft copper wire.

[0015] Optionally, the electric telescopic rod is fixed to the outside of the generator body by an annular plate on the bottom outer side, wherein:

[0016] The rotating mechanism includes a rotating plate and a drive shaft. The electric telescopic rod is connected to the upper end of the rotating plate, and the drive shaft is provided at the bottom of the rotating plate. The drive shaft passes through the fixing mechanism and is connected to the first baffle.

[0017] The fixing mechanism includes a mounting plate and screws. The mounting plate is fixed to the outside of the generator body by through screws. The mounting plate is L-shaped.

[0018] Optionally, the first baffle is provided with a sector gear at the end of the shaft, the sector gear is fixed, and the first baffle is connected to the second baffle through an auxiliary block on the bottom outer side. The second baffle is provided with a third gear on the outside of the shaft at the front end, the third gear meshes with the sector gear, a silicone strip is fixed at the front end of the second baffle, and three cooling fans are provided through the surface of the second baffle.

[0019] The pushing mechanism includes a collar and a long rod. The long rod is fixed to the left side of the auxiliary block. The auxiliary block is triangular. The upper end of the long rod is fixed with a collar, which is fitted onto the protrusion at the lower end of the mounting plate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1) In this invention, the connecting block is driven to descend. The connecting block is connected to the push rod on both sides via a rotating shaft. A rotating rod is installed inside the left side of the push rod. When the right end of the push rod descends, it will cause the push rod to drive the rotating rod to rotate. The push rod and the rotating rod are welded together. When the rotating rod rotates, it will cause the positioning device to rotate, thereby allowing the brake pad to contact the ground. The length of the brake pad is greater than that of the moving mechanism. The brake pad raises the generator body, causing the moving mechanism to leave the ground and fix its current position, making it convenient for maintenance personnel and preventing slippage. Moreover, the movement of the rotating rod will cause the first gear to rotate. The first gear meshes with the second gear, so the second gear will also start to rotate. A winding rod is set between the two second gears. The winding rod is driven to rotate, and at this time, the winding rod begins to unwind the wire, allowing the soft copper wire to gradually lengthen, thereby connecting the grounding body to the grounded ground. This ensures good grounding during maintenance. In addition, the grounding device can be rewound to avoid long-term friction between the grounding body and the ground when not in use, which is more conducive to extending the service life of the grounding device.

[0022] 2) In an optional solution, a first baffle and a second baffle are installed on the left, right, and rear sides of the generator body. Activating the electric telescopic rod retraction allows the rotating plate to rotate counter-clockwise, thereby using the bottom drive shaft to rotate the first baffle to a horizontal position. At this point, the first baffle is connected to the second baffle via an auxiliary block. A long rod is fixedly connected to the upper end of the other side of the auxiliary block, and the upper end of the long rod can rotate via a collar. When the first baffle rotates, the pushing mechanism drives the second baffle to move accordingly. Furthermore, the rotation of the first baffle causes the sector gear to drive the meshing third gear to rotate. The third gear then uses a rotating shaft to rotate the second baffle to a horizontal position. At this point, the first and second baffles are fully extended, preventing other objects or walls from adhering to the generator body, ensuring smooth airflow from the heat sink. To further ensure air circulation, a cooling fan is also installed on the second baffle to prevent hot air from accumulating on the outside of the generator body, thus improving external heat dissipation.

See also... Figures 1 to 8 As shown, the generator body 1 has four moving mechanisms 5 at its bottom. Each moving mechanism 5 includes a roller 501 and a first support plate 502. The roller 501 is located between the two first support plates 502. The length of the moving mechanism 5 is less than the length of the positioning device 8. The generator body 1 has a handle 6 at its upper end, which facilitates the movement of the device by the staff.

[0040] For example, the handle device 6 includes: a plastic strip 601, a fixing plate 602 and a bolt 603. The outer side of the plastic strip 601 is provided with anti-slip material. Both sides of the plastic strip 601 are fixed inside the fixing plate 602. The fixing plate 602 is connected to the generator body 1 by the bolt 603, which makes it convenient for the staff to lift the device.

[0041] For example, the braking mechanism 7 includes: a cylinder 701, a connecting block 702, a push rod 703, and a rotating rod 704. The cylinder 701 is fixed to the bottom of the generator body 1. The connecting block 702 is connected to the bottom of the generator body 1. Two push rods 703 are connected to the outside of the connecting block 702 through a rotating shaft. The rotating rod 704 is connected to the left side of the push rod 703. The rotating rod 704 is welded to the push rod 703. The rotating rod 704 can rotate inside the second support plate 9. Two positioning devices 8 are provided through the rotating rod 704. The positioning devices 8 on the left and right sides are mirror-distributed, which allows the positioning devices 8 to rotate.

[0042] For example, the positioning device 8 includes: brake pad 801, anti-slip pad 802 and triangular block 803. The upper end of the brake pad 801 is irregularly shaped, the bottom of the brake pad 801 is connected to the anti-slip pad 802, the left side of the anti-slip pad 802 is fixed to the triangular block 803, the two brake pads 801 pass through the outside of the rotating rod 704, and the outside of the rotating rod 704 also has two first gears 10 passing through, so that the first gears 10 follow the rotation.

[0043] For example, a grounding device 11 is provided at the front end of the first gear 10, and the grounding device 11 includes: a second gear 1101, a winding rod 1102, a soft copper wire 1103, an upper interface 1104, and a grounding body 1105. The second gear 1101 meshes with the first gear 10. A winding rod 1102 is provided between the two second gears 1101. A soft copper wire 1103 is wound around the outside of the winding rod 1102. The upper end of the soft copper wire 1103 is connected to the upper interface 1104, which is connected to the outer shell of the generator body 1. A grounding body 1105 is provided at the end of the soft copper wire 1103 to ensure the safety of the device.

[0044] For example, the electric telescopic rod 12 is fixed to the outside of the generator body 1 by an annular piece 1201 on the bottom outer side. The rotating mechanism 13 includes a rotating piece 1301 and a drive shaft 1302. The electric telescopic rod 12 is connected to the upper end of the rotating piece 1301, and the drive shaft 1302 is provided at the bottom of the rotating piece 1301. The drive shaft 1302 passes through the fixing mechanism 14 and is connected to the first baffle 15. The fixing mechanism 14 includes a mounting plate 1401 and screws 1402. The mounting plate 1401 is fixed to the outside of the generator body 1 by the through screws 1402. The mounting plate 1401 is L-shaped to prevent other devices from blocking the air outlet.

[0045] For example, a sector gear 1501 is provided on the rotating shaft at the end of the first baffle 15. The sector gear 1501 is fixed. The first baffle 15 is connected to the second baffle 18 through the auxiliary block 16 on the outer side of the bottom. A third gear 1802 is provided on the outside of the rotating shaft at the front end of the second baffle 18. The third gear 1802 meshes with the sector gear 1501. A silicone strip 1801 is fixed to the front end of the second baffle 18. Three cooling fans 19 are provided through the surface of the second baffle 18. The pushing mechanism 17 includes a collar 1701 and a long rod 1702. The long rod 1702 is fixed to the left side of the auxiliary block 16. The auxiliary block 16 is triangular. The collar 1701 is fixed to the upper end of the long rod 1702. The collar 1701 is fitted onto the protrusion at the lower end of the mounting plate 1401, thereby improving the heat dissipation effect.

[0046] In this embodiment, when using the microwave signal generator with a high-power vacuum tube, the roller 501 is in contact with the ground in the initial state, which facilitates the movement of the generator body 1 by the operator. When it is time to start work or to perform maintenance, the cylinder 701 can be activated to prevent the generator body 1 from moving. The cylinder 701 drives the connecting block 702 to descend. The connecting block 702 is connected to the push rod 703 on both sides via a rotating shaft. A rotating rod 704 is installed through the left side of the push rod 703. At this time, the right end of the push rod 703 descends, causing the push rod 703 to drive the rotating rod 704 to rotate. The push rod 703 and the rotating rod 704 are welded together. The rotation of the rotating rod 704 causes the positioning device 8 to rotate, thereby allowing the brake pad 801 to contact the ground. The upper end of the brake pad 801 has an irregular shape, which allows the position of the brake pad 801 to be fixed during rotation.

[0047] In this embodiment, an anti-slip pad 802 is provided at the bottom of the brake pad 801 to increase the friction with the ground. A triangular block 803 is fixed on the side of the anti-slip pad 802 so that the brake pad 801 can make good contact with the ground when rotating.

[0048] In this embodiment, the length of the brake pad 801 is greater than that of the moving mechanism 5. The brake pad 801 raises the generator body 1 as a whole, causing the moving mechanism 5 to leave the ground and fix its current position, making it convenient for staff to inspect and prevent slippage.

[0049] In this embodiment, the movement of the rotating rod 704 causes the first gear 10 to rotate. The first gear 10 meshes with the second gear 1101, so the second gear 1101 also begins to rotate. A winding rod 1102 is provided between the two second gears 1101, and the winding rod 1102 is driven to rotate. At this time, the winding rod 1102 begins to release wire, allowing the soft copper wire 1103 to gradually lengthen, thereby connecting the grounding body 1105 to the grounding ground, ensuring good grounding during maintenance.

[0050] In this embodiment, the grounding device 11 can be rolled back to avoid long-term friction between the grounding body 1105 and the ground when not in use, and the grounding wire is laid out while braking, which is more convenient for the staff to operate.

[0051] To prevent the generator body 1 from coming into close contact with other devices or walls, a first baffle 15 and a second baffle 18 are installed on the left, right, and rear sides of the generator body 1. Activating the electric telescopic rod 12 retracts the generator, allowing the rotating plate 1301 to rotate counterclockwise. This, in turn, drives the first baffle 15 to rotate via the bottom drive shaft 1302, bringing it to a horizontal position. At this time, the first baffle 15 is connected to the second baffle 18 via an auxiliary block 16. A long rod 1702 is fixedly connected to the upper end of the other side of the auxiliary block 16, and the upper end of the long rod 1702 can rotate via a collar 1701. As the first baffle 15 rotates, the pushing mechanism 17 moves the second baffle 18 accordingly. Furthermore, the rotation of the first baffle 15 causes the sector gear 1501 to drive the meshing third gear 1802, which in turn rotates the second baffle 18 to a horizontal position via a rotating shaft. At this time, the first baffle 15 and the second baffle 18 are fully deployed, which can prevent other objects or walls from adhering to the generator body 1, ensuring smooth airflow from the heat sink 4.

[0052] In this embodiment, in order to ensure the flow of gas, a cooling fan 19 is also provided on the second baffle 18 to prevent hot air from accumulating on the outside of the generator body 1. While limiting the contact distance, it can improve the heat dissipation effect and increase the service life of the overall device.
